Abstract (en)

The arrangement includes respectively a measuring resistance connected at a secondary side of the protection instrument or power switch arrangement, whereby their respective not permissible voltage or current value leads to a triggering of the respective protection instrument or switch arrangement. The converter arrangements are implemented through non-conventional, low-power current converters (WI) and/or through respective voltage converters (WU). The measuring resistances (RM) of the current and/or voltage converter are connected in parallel with adjustment modules (AM) formed respectively from resistance networks (RN) and adjustment fields (AF). The measuring resistances and the resistance networks are respectively positioned on common printed circuit boards (LP). The printed circuit boards are equipped with double conductor paths (LD) in the area of drill holes (BL), in such way, that at an adjustment in the area of a drilling hole, a partial resistance (RT) associated with it, is connected with a fixed resistance (RF) of the resistance network.

Abstract (de)

Die Erfindung betrifft Wandlereinrichtungen für Schutzgeräte und Leistungsschaltereinrichtungen, die beim Überschreiten nicht zulässiger Strom- und Spannungswerte zu Auslöseansteuerungen führen. Die Wandlereinrichtungen (WE) sind durch nichtkonventionelle, leistungsarme Strom- bzw. Spannungswandler realisiert, denen aus Widerstandsnetzwerken (RN) und Abgleichfeldern (AF) gebildete Abgleichmodule (AM) parallel geschaltet sind und deren Abgleich durch Bohrlochunterbrechungen von durchkontaktierten Doppel-Leiterbahnen erfolgt. <IMAGE>
